Synthèse ESCo Terres rares. Vers une utilisation responsable des terres rares tout au long de leur cycle de vie : quelles perspectives en termes de sobriété, recyclage et mode de production ?

Rare earths are metals that are of crucial interest for France. Their supply is a vital issue on many levels - industrial, technological, geopolitical, economic, environmental and health-related. The Rare Earths Collective Scientific Assessment (ESCo) is a CNRS initiative that aims to establish the state of scientific knowledge on the use of rare earths throughout their life cycle through study of sobriety and recycling practices along with changes to extraction and production methods. This document, available in English (secondary file), is the ESCo report; however, a summary (4p.) and the full report (800p. in french) are available on the dedicated web page on the CNRS website (https://www.cnrs.fr/en/nos-recherches/expertise-scientifique-collective/esco-terres-rares) or below (‘Related resources’).
